llvm dev - Jul 2011 - [LLVMdev] Is MachineLoop Simplify Form?

Is there any reason that we don't have isLoopSimplifyForm method in
LoopBase? Can I move it there?

I'll take a wild guess that it's because LoopSimplify doesn't run on
MachineLoops and lowering passes can invalidate it. You can always test for
individual loop properties that you need instead of calling isLoopSimplify. For
example, do you *really* need hasDedicatedExits()? If your MachineLoops
don't need it, then you should leave it's implementation LoopInfo.cpp.
